"All Of Us Are Dead"|Season 1|Episode 12 Final

After the students escape, they reach an abandoned neighborhood. Nam-ra senses some zombies. The students attempt to escape, but Dae-su's leg is injured, forcing them to stay and fight off the zombies. Woo-jin is bitten while saving his sister, resulting in Nam-ra killing him. During the escape, Nam-ra increasingly feels an urge to eat her friends, with voices in her head telling her to do so, and she almost bites On-jo. Driven by remorse and in order to not hurt her friends, Nam-ra abandons them and disappears in the neighborhood. The remaining six student survivors - Su-hyeok, On-jo, Dae-su, Hyo-ryung, Mi-jin and Ha-ri - reach an abandoned railway, where the military finally rescues them. Four months later, the government ends martial law in Hyosan, but continues to quarantine the residents. The six students sneak out of the camp and return to the remnants of their school. Nam-ra, who looks well and healthy despite remaining as a half-zombie, meets up with them. Nam-ra says there are a few others like her who escaped from the school and says she will return as she jumps from the rooftop, leaving the others staring after her. In a mid-credits scene, government officials remove the bodies of Byeong-chan's wife and son to another location.
